| DTC Strategy |
- Monitoring responsiveness of the HO2S
|
- Poor Connector Connection
- HO2S (Bank2/sensor1)
- ECM
|
| Enable Conditions |
- Detects the operational readiness of the O2 (up) sensor (Sensor tip temperature is higher than 640°C (1, 184°F) or maximum heating more than 30s or normal heating for 30s)
- HO2S forced simulation is activated
- P0420 monitoring is activated
- Battery voltage higher than 11V and lower than 16V
|
| Threshold value |
- HO2S response speed is too Late (ECM self-diagnosis)
|
| Diagnosis Time |
- 25 times per cycle air-fuel ratio control
|
| MIL ON Condition |
